The Dirty Bomb Nightmare
Israel may have struck Iran before it could build a fissile nuclear weapon, but the Islamic Republic can still cause tremendous destruction short of a nuclear explosion. If Khamenei wants to make good on his threats, his next step will likely be to hit Israel with dirty bombs to spread radiation over large sections of its urban areas.
The same strategy would satisfy Khamenei's desire for revenge against Arab states that help Israel. After all, if Jordan shoots down a missile with a radioactive warhead over its own territory, then the resulting radiation contamination it suffered would be, from Khamenei's perspective, divine retribution.

While its main nuclear facilities have been damaged, underground labs and dispersed storage sites may still hold usable material," Dr Krieg said, adding that "assembling a viable dirty bomb with significant dispersal impact involves logistical, safety, and secrecy challenges".
However, John Erath, senior policy director at the Washington, DC think-tank, the Centre for Arms Control and Non-Proliferation, points out that if Iran were considering building a dirty bomb, "it's kind of wasting a lot of enrichment".
He added: "It would, in theory, potentially put a lot of radiation out in the atmosphere and potentially make people sick over a wide area. So it exists mostly in theory. It's highly impractical and a little bit difficult to do in practice.
A bomb with uranium would be easy enough for Tehran to make—but may not make sense to use.
